Your english is very good.
It seems that you are just lazy to type correctly.
It would be much easier to get your point across with correct punctuation, believe me!

Try this:

echo $VARIABLE | sed 's/%20/ /g'

Or this to modify the file directly:

sed -i 's/%20/ /g' index.html

I can't help you with BASH, but if you could afford to do it in Python it's pretty simple:



print "Hello%20World!".replace("%20", " ")

If you want a really, really dirty way of doing it, you can try

line="Hello%20%3A%29"
eval `echo echo -e $line | sed 's/%\([A-F0-9]\{2\}\)/"\\\0"\`echo "ibase=16;obase=8;\1"|bc\`/g'`
which will replace any %## with its respective ascii symbol.

Beautiful isn't it?

wow thanks for the quick responces, I tried all of the above , but settled with the following. :-


VARIABLE1=$(echo $$VARIABLE2 | sed 's/ /30%/g')_

Which seems to work perfectly (until i break it) leaving the output of the sed command in $VARIABLE1.

Once again thanks for the heads up guys :)

Easier:
var1="AAA%20BBB%20CCC"
var1=${var1//'%20'/" "}
echo $var1
=
AAA BBB CCC
